Description: Abstract
The Lucene Server project is an attempt to extend the Jakarta Lucene tool with server capabilities.
Lucene is a robust Java API that enables you creating indexes from text sources and perform powerful searches on these indexes. With Lucene, creating an index must be done programmatically and there are almost no possibilities of integrating index management in a distributed environment. In other words, out of the box, Lucene is suitable for integrating indexing and searching possibilities in a single application but not for providing index/search services for multiple applications.
The Lucene Server project comes with a Java API that propose the following
make it easy to create indexes in a declarative way by simply providing an XML configuration document.
make it easy to personalize the way Lucene must handle different kind of data sources.
provide services for index management and searching that can be accessed from several applications.
enable batch tasks scheduling. Platform: |

Description: Recently, IEEE 802.16j multi-hop relay network is proposed to increase data rate and coverage of the IEEE 802.16e networks. The Relay Station (RS) is introduced to relay the data from MR-BS to SS/MS or from SS/MS to MR-RS. We have studied the research area for a whole, and we proposed some improvements that could decrease the congestion opportunity of non-transparent RS using distributed scheduling. We have to modify the NIST WiMAX module which is implemented under the NS-2 in order to test the correctness of our proposed scheme. Subversion and Google-code-hosting are used to manage the project versions, thus we could be easy to modify the NIST module to support the functions of RS. Platform: |

Description: Grid technologies have progressed towards a service-oriented paradigm that enables a new way
of service provisioning based on utility computing models, which are capable of supporting diverse
computing services. It facilitates scientific applications to take advantage of computing resources
distributed world wide to enhance the capability and performance. Many scientific applications in areas
such as bioinformatics and astronomy require workflow processing in which tasks are executed based on
their control or data dependencies. Scheduling such interdependent tasks on utility Grid environments need
to consider users’ QoS requirements. In this paper, we present a genetic algorithm approach to address
scheduling optimization problems in workflow applications, based on two QoS constraints, deadline and
budget.

Description: 蚁群算法(ant colony algorithm，简称ACA)是20世纪90年代由意大利学者M．Dorigo等人首先提出来的一种新型的模拟进化算法．它的出现为解决NP一难问题提供了一条新的途径．用蚁群算法求解旅行商问题(TSP)、分配问题(QAP)、调度问题(JSP)等，取得了一系列较好的实验结果．虽然对蚁群算法研究的时间不长，但是初步研究已显示出蚁群算法在求解复杂优化问题(特别是离散优化问题)方面具有一定的优势，表明它是一种很有发展前景的方法．蚁群算法的主要特点是：正反馈、分布式计算．正反馈过程使它能较快地发现问题的较好解；分布式易于并行实现，将它与启发式算法相结合，易于发现较好解．-ACO (ant colony algorithm, referred to as ACA) is the 1990s by the Italian scholar M. Dorigo, who first proposed a new type of simulated evolutionary algorithm. It appears to solve NP-hard problem provides a new way. Ant colony algorithm for traveling salesman problem (TSP), distribution (QAP), scheduling problems (JSP), etc., made a series of good results. Although the ant colony algorithm is not long, but preliminary studies have shown that the ant colony algorithm in solving complex optimization problems (in particular, discrete optimization problem) has certain advantages, that it is a promising approach. The main features of ant colony algorithm is: positive feedback, distributed computing. Positive feedback process so that it can quickly find a better solution of the problem distributed easy-to-parallel implementation, it would be combined with the heuristic algorithm, easy to find better solutions.

Description: 使用Socket实现一个socket服务器与多个socket客户端通信
在分布式调度系统中，如果要实现调度服务器与多台计算节点服务器之间通信，采用socket来实现是一种实现方式，当然我们也可以通过数据存储任务，子节点来完成任务，但是往往使用数据作为任务存储都需要定制开发，要维护数据库中任务记录状态等等。开发的东西还是有点多，而且还不够灵活。因此，我个人是比较偏向于使用socket来实现任务的调度工作。原因：使用socket实现调度比较灵活，而且扩展性都比较好。
实现思路：调度服务器要实现调度工作，它必须与所有计算节点之间建立连接。而且他需要知道每台计算节点的任务状况，因此服务器节点必须存储与所有计算节点的socket连接对象。
在客户端唯一需要知道的就是它归属的调度服务器的通信IP和端口，因此client是发送连接的主动方，由调度服务器监听是否有client请求建立连接，当建立连接成功后，把该连接信息存储到一个结合中以便监控client的存货状态及通信使用。(Using Socket to realize the communication between a socket server and multiple socket clients
In a distributed scheduling system, if we want to realize the communication between a scheduling server and a number of computing node servers, the implementation of socket is an implementation. Of course, we can also accomplish the task by data storage tasks and sub nodes, but the use of data as a task storage needs to be customized and developed. Protect the status of the task record in the database and so on. There are still a lot of things to develop, and not flexible enough. Therefore, I personally prefer to use socket to achieve task scheduling. Reason: using socket to implement scheduling is more flexible and expansibility is better.) Platform: |
